Abstract: A method and structure for electrically and mechanically interconnecting an array of printed circuit board contacts to an array of module contacts with a plurality of deformable resilient electrical conductors with two ends. Each of the conductor ends are electrically connected to one of the contact arrays. A portion of the conductor may deform longitudinally and laterally responsive to movement of the printed circuit board relative to the module responsive to heating and cooling cycles and mechanical vibrations, while maintaining the electrical connection of the contact arrays. An interposer with apertures extending through the interposer carries the conductors in the apertures and is used to align the conductors with the contacts. A method for excluding a rigid adhesive means from a portion of the resilient conductor is also taught.

Abstract: An interposer member having strategically positioned apertures for electrically connecting an electronic device to a circuitized substrate. The member includes a homogeneous elastomer core having strategically positioned apertures. The apertures are positioned through the member approximately equidistant between adjacent plated through holes and/or conductive pads. Such positioning relieves stress from the plated through holes and/or conductive pads, and increases the contact compliancy of the member.

Abstract: An electronic subassembly comprises a printed circuit board and an electronic module, particularly a ceramic module, electrically connected to one another through a planar interposer. The interposer comprises an insulator sheet and electrical spring elements joining contact sites on the module with contact pads on the PCB. The invention includes modifications that improve the integrity of electrical connections between the printed circuit board and the electronic module. This is achieved by compensating for non-planarity between the surfaces of the interposer and the module, particularly resulting from a convex curvature of the module, by minimizing relative movement, such as rocking in the x-z and y-z planes. It also includes modifications to the suspension of the module within the interposer housing to reduce the effects caused by any sliding that may occur between the interposer and the module in the x-y plane.

Abstract: The present invention provides a method and structure for connecting a module to a printed circuit board, wherein a substantially rigid interposer having resilient conductors is disposed between a module and a printed circuit board. A clamping means urges the module and printed circuit board toward each other with compressive force upon an interposer positioned therebetween, preferably causing the module and printed circuit board to deform and thereby align their electrical contacts with the surfaces of the interposer. The interposer further comprises a plurality of apertures, each aperture further having a deformable resilient conductor means for connecting a module contact to a PCB contact. The conductor is deformable in shear, which may travel and, therefore, makeup the CTE dimensional mismatch between the module and the PCB. The conductors are detachable, electrically connecting the module and PCB contacts without the requirement of solder or other permanent means.

A feature of the invention is that an anode container has an interior cross-sectional area, at or near a lower end thereof, that is larger than an interior cross-sectional area of an upper end thereof. An anode-receiving container also has a body with a plurality of sides and a lower end having a larger cross-sectional interior area than an upper end. The container may also include punched out apertures positioned to provide strength to the container and an apparatus to vibrate the container coupled to a lower end of the container.

Abstract: An electronic package including as part thereof a thermally conductive arrangement for restricting thermal fluid material motion about a heat-generating device, thereby assuring effective heat transference from the heat-generating device (e.g., module) to a cooling member (e.g., spaced heat sink), this arrangement preferably including: (1) a thermal fluid (e.g., thermal grease); and (2) structural elements (e.g., wire mesh, heat sink ridges, etc.). For restricting fluid movement, sealing structures (e.g., external gaskets) may be used to further assure fluid containment to a specified location. Pressure generation means (e.g., a plunger) can be used to increase fluid pressure when pressure droppages occur.

Abstract: A composite cable has a reinforcing layer with conductors disposed on opposed planar surfaces. Dielectric film layers electrically separate the conductors on the planar reinforcing layer from respective layers of additional conductors. The flexible cable is manufactured by laminating a layer of dielectric film and a layer of electrically conductive material onto both sides of a double clad core which provides a strain relief reinforcement for the cable.

Abstract: A flexible circuitized interposer (50) and method of making same wherein the interposer includes at least one flexible circuitized substrate (53) having a dielectric (e.g., polyimide) layer (54) with a conductor (55) and plated elements (56), e.g., copper pad, including possibly with dendrites (57) thereon for enhanced connection, an apertured support member (58) aligning with the conductor, and a support member (60) having the apertured member thereon. When the interposer is engaged, the flexible circuitized substrate (53) is depressed within the aperture (59). Various alternatives, including a support (60") formed with compression portions (69) that extend into respective apertures (59) in the support member (58), and an interim, compressible support (60""), are disclosed. Flexure is also enhanced by utilization of patterns of one or more apertures (64) in the flexible substrate relative to and substantially surrounding the positioned conductors (56).

Abstract: An elastomeric structure including two layers, the first having patterned openings therein and adjacent web members, the second including a patterned array of upstanding projections. The openings and projections may be of cylindrical, rectangular, or other configurations and are oriented in highly dense patterns. The elastomeric is positioned with and attached to a base member having a sidewall substantially as high as the corresponding external side surface of the elastomeric's first layer. The sidewall constrains the elastomeric during compression. The invention thereby substantially prevents lateral expansion of the elastomeric's side surface and lateral deflection of both layers, resulting in a uniform distribution of compressive forces on the upstanding projections.

Abstract: An electrical connector for coupling two circuitized substrates (e.g., a ball grid array module and a printed circuit board) wherein the connector includes a base member fixedly secured (e.g., soldered) to the printed circuit board and having one substrate oriented therein. The connector further includes a 2-part retention member including one part movably oriented in the base and a second part for directly engaging the retained substrate to cause it to move downwardly (and thus in a completely different direction than the direction of rotation of the movable one part within the base) to thereby provide effective connection between substrates. An interposer may be used if desired. An information handling system including a microprocessor and connector electrically coupled thereto is also disclosed.

A method for making an elastomeric support member for use in such a circuitized substrate is also provided.
